you have 2 week to think about it before they become more expensive.
you have 41 days to think about it before you can't buy them until their genesis block goes live.

you can't trade them until then, so you're taking a huge risk.
I like ethereum and I think those guys deserve some credit for what they've accomplished sofar, but I want to see any of those tokens stand the test of time before I am putting any money in stuff like MSC, NXT, XCP, ETH etc...
